6 Claims. (Cl. 252--8.57)

This invention relates to compositions and methods for glazing natural furs and, more particularly, to a glazing composition adapted for application to fur by spraying which will not only glaze the fur but also make the fur smooth and soft While eliminating the natural tendency of the fur to attract and hold particles of dust and dirt.

The composition of the present invention comprises an aqueous dispersion of a dialkyl dimethyl ammonium salt, a silicone oil and a tertiary amine or a polyalkylene ether of an alkylated phenol.

The above mentioned dialkyl dimethyl ammonium salt is ordinarily the chloride. Each alkyl group contains from 8 to 18 carbon atoms. By way of examples, the alkyl group may be derived (by reduction of the carboxyl group) from soya fatty acid, tallow, hydrogenated tallow, coconut fatty acid, stearic acid and the like.

The above mentioned silicone oil is a polydimethyl or polydiethyl siloxane.

The above mentioned tertiary amine has the following structural formula:

(CHz-(3H -O),-H wherein R signifies an alkyl group containing from 8 to 18 carbon atoms and wherein x and y signify numbers totalling from 2 to 10. The alkyl group may be derived from a fatty acid (by reduction of the carboxyl group), such as soya fatty acid, coconut fatty acid or stearic acid.

The above mentioned polyethylene glycol ether of an alkylated phenol is a condensation product of from 2 to molecules of ethylene oxide with one molecule of an alkyl phenol wherein the alkyl group contains from 8 to 10 carbon atoms, for instance, octyl, nonyl and decyl phenol.

The above mentioned four materials (quaternary ammonium compound, tertiary amine, polyethylene glycol ether of an alkylated phenol and silicone oil) are all available in commerce.

The weight proportions of the above mentioned materials are the following:

From 1 to 4 ounces of the quaternary ammonium salt are used with /2 to 2 ounces of silicone oil and from 1 to 4 ounces of tertiary amine or alkyl phenol ether. These amounts are suitably dispersed in 1 gallon of water by a method described hereinbelow. If desired, a greater amount of water may be used, but then the composition is not diluted as much as indicated hereinbelo-W before being used.

In preparing the compositions of the present invention, a quaternary ammonium salt is heated with /2 of the water to a temperature not above 200 F. until a thick gel is formed. Next, the other ingredients and the remainder of the water (at room temperature) are added and the resulting mixture is agitated whereby a stable emulsion is formed.

Two examples of compositions according to this invention are given as follows.

The composition of the first example contains 4 ounces of a percent solution (in i'sopropyl alcohol) of dialkyl dimethyl ammonium chloridewherein the alkyl groups are derived from soya fatty acid; 1 ounce ofpolydimethyl siloxane; 1 ounce of nonyl phenol condensed with ethylene oxide in a molecular ratio of 1:10; and water to make 1 gallon.

The composition of the second example is similar to that of the first example, except. that, for the nonyl phenolethylene oxide condensation product, I substitute a tertiary amine having the above indicated structural formula wherein the alkyl group is derived from soya fatty acid and wherein x and y total between 8 and 10.

In use, one part of my composition is diluted with 4 parts of water. The resulting diluted emulsion is sprayed onto the fur to be glazed with an air spray gun. The garment is then ironed with an ironing machine at about 325 F.

In my composition, the quaternary ammonium salt serves to render the fur soft and smooth; the silicone oil renders the fur glossy and shiny; and the tertiary amine and the alkyl phenol ether serve both to emulsify the other ingredients in the water and to render the fur susceptible to wetting and penetration by my composition.

The tertiary amine, when used, also eliminates the tendency of the fur to attract and hold particles of dust and dirt.

Many details may be varied without departing from this invention and it is therefore not my purpose to limit the patent granted on this invention otherwise then necessitated by the scope of the appended claims.

The invention is claimed as follows:

1. A fur glazing composition suitable for application by spraying and comprising water having dispersed therein a dialkyl dimethyl ammonium salt wherein group contains from 8 to 18 carbon atoms, a silicone oil selected from the group consisting of polydimethyl siloxane and polydiethyl siloxane and a material selected from the group consisting of a polyethylene glycol ether of alkyl phenol being a condensation product of one molecule of an alkyl phenol wherein the alkyl group contains from 8 to 10 carbon atoms with from 2 to 10 molecules of ethylene oxide and a tertiary amine having the following structural formula:

ILR

3HgCHzO) H wherein R signifies an alkyl group containing from 8 to 18 carbon atoms and wherein x and y are numbers totalling from 2 to 10.

2. A fur glazing composition according to claim 1 comprising from 1 to 10 parts by Weight of said ammonium salt, from /2 to 2 parts of said silicone oil and from 1 to 4 parts of said selected material.

3. A composition according to claim 2 in which said selected material is said alkyl phenol ether.

4. A composition according to claim 2 in which said selected material is said tertiary amine.

5. A method of preparing a fur glazing composition which comprises heating at not above 200 F. a mixture of water and a dialkyl dimethyl ammonium salt wherein each alkyl group contains from 8 to 18 carbon atoms until a thick gel has been formed, and thereafter adding to said gel and stirring additional water, a silicone oil selected from the group consisting of polydimethyl siloxane and polydiethyl siloxane and a material selected from the group consistng of a polyethylene glycol ether of alkyl phenol being a condensation product of one molecule each alkyl of an alkyl phenol wherein the alkyl group contains from 8 to 10 carbon atoms-with from 2 to 10 molecules of ethylene oxide and a tertiary amine having the following to 18 carbon atoms and wherein x and y are numbers 10 totalling from 2 to 10.

6. A method according to'claim 5 in which said ammonium salt amounts to from 1 to 4 parts by weight, said silicone oil amounts to from /2 to 2 parts and said selected material amounts to from 1 to 4 parts. 15 pp. 33-52.
